deep tendon reflex deep tendon reflex. n. Tonic contraction of the muscles in response to a stretching force, due to stimulation of muscle proprioceptors. deep tendon reflex (DTR) a brisk contraction of a muscle in response to a sudden stretch induced by a sharp tap by a finger or rubber hammer on the tendon of insertion of the muscle. Absence of the reflex may be caused by damage to the muscle, peripheral nerve, nerve roots, or spinal cord at that level.

Ultrasound shows high sensitivity in rotator cuff Subscapularis tendon tears: an isolated subscapularis tendon tear is rare and is often caused by trauma when a person is moving and falls with the shoulder in extension and abduction. Particularly in children, the tear often includes an avulsion fragment of the lesser tuberosity, on which the subscapularis inserts.Full-thickness tears can be large or small. In large full-thickness tears, the rotator cuff tears completely and the fragments retract from each other. Hence, no cuff is visualized.

Muscle-Tendon-Bone Connection A tendon is tough, but flexible, band of fibrous connective tissue. One end of the tendon connects to muscle. The other end the tendon connects to bone. Contraction of the muscle pulls on the tendon, causing the tendon to pull the bone. In this way, tendons play an important role in muscle control of the body.Tendons are made of parallel collagen fibers running the length of the tendon. These collagen fibers give the tendon its strength. Tendons grow into the bone creating a connection that is extremely strong and hard to break.he other end the tendon connects to bone. Contraction of the muscle pulls on the tendon, causing the tendon to pull the bone. In this way, tendons play an important role in muscle control of the body. Tendons are made of parallel collagen fibers running the length of the tendon.

- Structure and Function of Tendon. The function of a tendon is to transmit force created by the muscle to the bone and to generate movement; thus, the tendons are part of a bone-tendon-muscle-tendon-bone complex.The tendon is composed primarily of type I collagen, the major fibrillar collagen in the body, organized into fibrils.endons may heal through a conservative treatment, or may require surgery. The surgical approach involves repairing the torn tissue back to its original position (or as close as possible), with the tendon-bone or tendon-tendon attachment requiring months to be complete.

Tendon Injuries in Horses A tendon is defined as a fibrous cord of connective tissue continuous with the fibers of a muscle and attaching the muscle to bone or cartilage--a muscle to bone connection. A ligament is defined as a band of tissue connecting bone or cartilage, serving to support and strengthen joints--a bone to bone connection.

Insertional Achilles Tendinitis The Achilles tendon is the largest tendon in the body. It connects your calf muscles to your heel bone and is used when you walk, run, climb stairs, jump, and stand on your tip toes. Although the Achilles tendon can withstand great stresses from running and jumping, it is also prone to tendinitis, a condition associated with overuse and degeneration.

- A tendon, or sinew, is a cord of tissue that attaches the end of a muscle to a bone or other part of the body. It is composed of bundles of white fibrous tissue surrounded by a sheath. This tissue enters the bone and blends with the fibers of the bone. A tendon is inelastic but flexible and very strong.

Deep Fascia Human Anatomy » Basic Anatomy » Deep Fascia. Deep fascia is the dense fibrous connective tissue that interpenetrates and surrounds the muscles, bones, nerves and blood vessels of the body. It is in the form of a fibrous sheet which invests the body beneath the superficial fascia.

tendon [ten´don] a cord or band of strong white fibrous tissue that connects a muscle to a bone. When the muscle contracts it pulls on the tendon, which moves the bone. Tendons are extremely tough and are seldom torn, even when an injury is severe enough to break a bone or tear a muscle. One of the most prominent tendons is the achilles tendon. Frequently injured tendons.

Anatomy Like a rubber band, tendons are under tension as they connect the muscle to the bone. If a tendon is torn or cut, the ends of the tendon will pull far apart, making it impossible for the tendon to heal on its own. Because the nerves to the fingers are also very close to the tendons, a cut may damage them, as well.escription. A torn or cut tendon in the forearm, at the wrist, in the palm, or along the finger will make it impossible to bend one or more joints in a finger. Because flexor tendons are very close to the surface of the skin, a deep cut will most likely hit a flexor tendon.

- Deep Tendon Reflexes. Using a reflex hammer, deep tendon reflexes are elicited in all 4 extremities. Note the extent or power of the reflex, both visually and by palpation of the tendon or muscle in question.

Achilles Tendon Injury - Including Achilles Tendinitis and Achilles Tendon Rupture The Achilles tendon is the largest, strongest tendon in the human body. Tendons are long, tough cords of tissue that connect muscle to bone. The Achilles tendon is located in the back of the heel and connects the heel bone to the calf muscle.

Deep Tendon Reflexes Deep tendon reflexes are often rated according to the following scale: 1  0: absent reflex. 2  1+: trace, or seen only with reinforcement. 3  2+: normal. 4  3+: brisk. 5  4+: nonsustained clonus (i.e., repetitive vibratory movements) 6  5+: sustained clonus.

deep tendon reflex deep tendon reflex (DTR) a brisk contraction of a muscle in response to a sudden stretch induced by a sharp tap by a finger or rubber hammer on the tendon of insertion of the muscle. Absence of the reflex may be caused by damage to the muscle, peripheral nerve, nerve roots, or spinal cord at that level. A hyperactive reflex may indicate disease of the pyramidal tract above the level of the reflex arc being tested. Generalized hyperactivity of DTRs may be caused by hyperthyroidism. Kinds of DTRs include Achilles tendon reflex, biceps reflex, brachioradialis reflex, patellar reflex, and triceps reflex.

Tendon Healing Mechanobiology Tendons consist of collagens, proteoglycans, glycoproteins, water and cells. Tendons are rich in collagens with the most abundant tendon component being type I collagen, constituting about 60% of the tendon and about 95% of the total collagen.The remaining 5% consist of type III and V collagens. In normal tendons, type III collagen is mainly located in the endotenon and epitenon.: TGF-beta is active during the inflammatory and repair phases of tendon healing. TGF-beta plays a major role in the repair of injured tendons. TGF-beta 1 aids an extra cellular matrix deposition; however, it’s over expression results in tissue fibrosis. TGF-beta 2 functions similarly to TGF-beta 1.

Muscles and Tendons of the Rotator Cuff The rotator cuff is the group of muscles and tendons that surround the shoulder joint. The rotator cuff is important for normal shoulder mobility, strength and function. Injuries to the rotator cuff, including rotator cuff tendonitis and rotator cuff tears, are common conditions that cause shoulder pain. Often doctors will discuss problems in terms of the rotator cuff as a whole, or they may describe injuries to specific tendons and muscles of the cuff.

- While deep tendon reflexes involve a single connection between afferent and efferent neurons (i.e., a monosynaptic reflex), the expression of a deep tendon reflex requires additional spinal connections.

What Is Deep Tissue Massage? Deep tissue massage is a type of massage aimed at the deeper tissue structures of the muscle and fascia, also called connective tissue. Deep tissue massage uses many of the same movements and techniques as Swedish massage, but the pressure will generally be more intense.

Physical Assessment - Chapter 8 Neurological System To assess deep tendon reflexes: 1  Encourage the patient to relax the arm or leg being tested. 2  Position the arm or leg so the appropriate tendon is slightly stretched. 3  Hold the reflex hammer lightly and swing it freely in an arc. 4  Strike the tendon with a brisk downward stroke, then lift up on the hammer immediately.

Finger They insert by tendons to the phalanges of the fingers. The deep flexor attaches to the distal phalanx, and the superficial flexor attaches to the middle phalanx. The flexors allow for the actual bending of the fingers. The thumb has one long flexor and a short flexor in the thenar muscle group.
